PAL first-timer seeks help

I am a first-time PAL wearer with this prescription:

-3.00 -1.00 x100
-2.75 -1.25 x080
Add: +1.75

I have these frames (50-19-140):

http://www.framesdirect.com/framesfp/Modern_Optical-tgsgr/r.html

The laser markings on the lenses indicate they are Solamax Spectralite.

I have gone back for a few adjustments, but things are still not right.  I'm
trying to determine if the problem is me (need to "adapt"), the fitting or
the lens (wrong for the frame, wrong for the Rx, wrong for my lifestyle).

Here are the details:

1. They are good for driving and long distance in general.

2. Intermediate vision is not very good.  When passing people in the hallway
at work, they are often out of focus/distorted.  Sitting at a long dinner
table or in a restaurant, there is a lot that is out of focus/distorted.

3. I have to raise my head quite a bit to get a good focus when reading
small print.

4. I do a lot of computer work, and that is a mixed bag.  Visual clarity
depends on the location and tilt of the monitor.  Using a laptop on a desk
is pretty bad unless I increase the font size.

5. I really love my peripheral vision, and tend to move my eyes, not my
head, when I want to see something that is not right in front of me.  This
was not a problem with my single vision lenses, but it sure seems to be a
big problem now ;-)

In a nutshell, it is almost as if the distance and near zones are not tall
enough. Am I describing the need for a bifocal?

I would appreciate any insights and suggestions that you have.  I realize
that there is no perfect lens, but perhaps there is something better than
Solamax for the frames and lifestyle that I have.  They are less than 2
weeks old, and I think I can ask for another lens, though they may only
offer me a single vision or bifocal.  But I would be interested in alternate
lens suggestions in the event that they offer me a different PAL.

Thanks.

Fitting involves making sure that the optical center of the lens is
installed in the frame at the proper position (left/right and up/down) for
the way the frame sits on your face and where your pupil is located. The
lens is ground on a sphere and then cut to fit your frame, so getting the
optical center correct is not as easy as it seems. One way to tell if the
fitting is the problem is to move the frame around on your face and see it
that helps, but that may be difficult to do because of your nosepads, etc.

Lift your frames up just a little and see if your distance vision is still
OK. Then check the reading area and see if it improves. If lifting up the
frame just a little helps, then your lens may be installed at the wrong
fitting height. This might explain your problem with the reading area.

Intermediate vision on any progressive is not very good. The useable portion
of the lens looks like an hour glass, and the intermediate area is a narrow
area connecting the distance and reading area. However, the Solamax is not
the best design for intermediate vision.

The reading area is at the bottom of the lens. There is no way around this.
Move your reading material lower. Moreover, the reading area is
approximately 1/3 the width of the lens at best.

See 2. above.

Progressive wearers have to move their head more often. You will adjust to
this.

If you don't mind the lined bi-focal, you will have superior vision, but no
intermediate vision (unless you get a tri-focal).

Thank you for this excellent information.

Based on the info below, is there a better lens for the intermediate,
without sacrificing the distance and near?

Thanks.

When you went back for adjustments, did they re-mark the lens to confirm the
fitting cross position and powers? If not, have this done asap.

Considering hte Rx and first time use I'd say everything sounds reasonably
normal. What we can't know is if the lens is positioned optimally- short as
possible back vertex distance with the fitting cross +/- 1mm central pupil.
Knowing that this needs to be done is one thing, making it happen is another.
That said, I'd give it another week or two for the brain to adapt, but if your
very uncomfortable a second opinion would not be out of line.

Hope this helps,

Thank you, Robert, this was helpful.

The lenses were NOT remarked.  I will stop by soon and ask that he do that.

One thing I noticed is that some days are better than others.  I wonder if
that due to adaptation, or a difference in the way the frames are positioned
(possibly indicating a bad fit??).
